Implementation Guide

Feature: Simple Word Forms Provider

This feature demonstrates creating a simple provider for generating word forms, allowing efficient recognition and conversion between singular and plural forms.

Overview

The SimpleWordFormsProvider class implements the IWordFormsProvider interface, enabling customization of word form handling during searches. Implementation Steps:

1. Define Word Forms Logic

Implement logic for converting words into their respective forms:

using System;
using System.Collections.Generic;

namespace GroupDocs.Search.Dictionaries
{
    public class SimpleWordFormsProvider : IWordFormsProvider
    {
        public string[] GetWordForms(string word)
        {
            List<string> result = new List<string>();

            // Handle plural to singular conversion for words ending in 'es'
            if (word.Length > 2 && word.EndsWith("es", StringComparison.InvariantCultureIgnoreCase))
            {
                result.Add(word.Substring(0, word.Length - 2)); // Remove the last two characters
            }

            // Handle plural to singular conversion for words ending in 's'
            if (word.Length > 1 && word.EndsWith("s", StringComparison.InvariantCultureIgnoreCase))
            {
                result.Add(word.Substring(0, word.Length - 1)); // Remove the last character
            }

            // Handle singular to plural conversion for words ending in 'y'
            if (word.Length > 1 && word.EndsWith("y", StringComparison.InvariantCultureIgnoreCase))
            {
                result.Add(word.Substring(0, word.Length - 1) + "is"); // Replace 'y' with 'is'
            }

            // Add plural forms
            result.Add(word + "s");
            result.Add(word + "es");

            return result.ToArray();
        }
    }
}
2. Configure the Index to Use Custom Word Forms Provider

Integrate your custom provider into the search configuration:

using GroupDocs.Search;
using GroupDocs.Search.Options;

namespace YourNamespace
{
    public class WordFormsProviderConfiguration
    {
        public void ConfigureSearch()
        {
            string indexFolder = "@YOUR_DOCUMENT_DIRECTORY/WordFormsProvider/Index";
            string documentsFolder = "@YOUR_DOCUMENT_DIRECTORY/Documents";

            Index index = new Index(indexFolder);
            index.Add(documentsFolder);

            // Set the custom word forms provider to handle plural and singular variations
            index.Dictionaries.WordFormsProvider = new SimpleWordFormsProvider();

            SearchOptions options = new SearchOptions { UseWordFormsSearch = true };
            string query = "mrs";
            SearchResult result = index.Search(query, options);
        }
    }
}

Troubleshooting Tips

  • Ensure all dependencies are correctly installed.
  • Verify directory paths in the configuration code.

Practical Applications

Implementing a custom word forms provider can enhance search functionality in various domains:

  1. Library Catalog Systems: Improve search capabilities for books, titles, or descriptions irrespective of singular/plural form.
  2. Legal Document Repositories: Enhance document retrieval by recognizing legal terms and their variants.
  3. Content Management Systems (CMS): Enable intuitive content searches across articles, blogs, and news sites.

Performance Considerations

Optimizing Performance

  • Regularly update your index to reflect the latest document changes.
  • Use asynchronous methods to prevent blocking operations in your application.

Resource Usage Guidelines

  • Monitor memory usage when processing large batches of documents.
  • Adjust indexing configurations based on system resources and requirements.

Conclusion

This tutorial guided you through setting up GroupDocs.Redaction for .NET and implementing a custom word forms provider. This setup enhances search functionality by recognizing various word forms, making your application more versatile and user-friendly. To further enhance your skills, explore additional features of GroupDocs.Search or experiment with other document processing capabilities.
